I tried four, 5 minute recordings in sequence, with a 1 minute gap between them. That worked OK.
Then I tried four more recordings with no gap between them. The next recording started at the same time the previous recording ended. That failed after the first recording.
Each channel was on a different satellite, switching between fixed dishes. I haven't tried this with a motorized dish.
The recorded files are labeled .ts They are just a single channel, not the entire mux.
A few other things. I used the editor on a PC to change the order of the satellites. After flashing the .db to the receiver, they were in that order under Satellite Installation, but not in the list that comes up when hitting the Sat button. Can't get that list ordered the way I want it.
On 103 w Ku I used the editor to change the beach cam audio to WCPE. It would play the station for about 1 second, and then switch to the apid defined in the table. Changing the sid to another number prevented this from happening. This may be common or not in other receivers. But don't recall needing to do this.
The banner screen that comes up for each channel lists the pids in hex, but the editor wants pids in decimal.
